Answer 1

x⁴+4+4x²+8x²=6x³+12x

use hit and trail method , maybe it helps

Answer 2

$\Large\bf\color{teal}{answer:}$

$\bf{To~solve:}$

$\tt{~~~~~~~~~~~~~(x^{2}+2)^{2}+8x^{2}=6x(x^{2}+2)}$

$\tt{= \implies [~(x^{2})^{2}+2(x^{2})(2)+(2)^{2}]+8x^{2}=6x^{1+2}+12x}$

$\tt{= \implies (x^{4}+4x^{2}+4)+8x^{2}=6x^{3}+12x}$

$\tt{= \implies x^{4}+12x^{2}+4=6x^{3}+12x}$

$\tt{= \implies {\underline{\boxed{\bf x^{2}-6x^{3}+12x^{2}+12x=-4}}}}$
